Description

Technical Field

[0001] The utility model relates to the technical field of electric meters, in particular to an electric meter which is convenient for modular installation. Background Art

[0002] An electric meter is an instrument used to measure electrical energy. It records the amount of electricity consumed by the user and charges electricity fees accordingly. Common types of electric meters include electromagnetic meters and electronic meters. During the installation of traditional electric meters, the installation efficiency is low due to the complex structure and cumbersome installation steps. In addition, during the installation of traditional electric meters, the accuracy and stability of the electric meters are easily affected due to the loose connection between components or irregular installation.

[0003] At present, in order to avoid the above problems, modular electric meters are usually directly selected. This type of modular electric meter has the advantage of being easy to install in a modular manner. The invention patent with the authorization announcement number CN115629228B discloses a modular electric meter and an installation method, including a box body, the box body is a hollow structure, a window is arranged on one side of the box body, and a case is arranged inside the box body at the position of the window, the electric meter is installed inside the case, a plurality of groups of wiring components are installed on the side opposite to the electric meter in the case, a plurality of groups of terminal blocks are arranged on the side opposite to the wiring components on the electric meter, the plurality of groups of wiring components are adapted to the plurality of terminal blocks, and the wiring components adaptively switch between the conductor and the insulator according to the contact with the electric meter to control the power-on and power-off state of the terminal blocks. The modular electric meter and the installation method of the application are provided with a wiring component and cooperate with the integrated circuit inside the box body. When installing, only the wiring component needs to be plugged into the terminal block on the electric meter to complete the installation, so that the electric meter is modularly installed without repeatedly removing the wires, thereby improving the efficiency of the installation and replacement of the electric meter.

[0004] Although this technical solution has the advantage of being able to install the meter in a modular manner without repeatedly removing the wires, thereby improving the efficiency of meter installation and replacement, when this technical solution is used, the motor is installed at the bottom of the box. Since the motor generates heat when it is working, the heat will dissipate upward, further causing the heat to enter the box, affecting the normal heat dissipation in the box. In addition, the motor is directly exposed to the outside, lacks corresponding protection components, cannot be protected, and is easily damaged by collision. In view of this, we propose an electric meter that is easy to install in a modular manner. Utility Model Content
